Hi, I just bought mine Nexus 5x few weeks ago, and 1 day after I started hear about the hardware bootloop problem. It made me scared.
I started searching about the problem and, until now, the conclusion about the problem is the phone gets heat and melt the solders of processor. That's a "comum" problem in LG phones, LG G4 have the same problem.
"-Ok, but, what causes that?"
My opinion, as lay, it is caused by cheap USB-C Cables and/or wall adapter. Fast charger adapters can also be a big problem. (Source: http://www.makeuseof.com/tag/buy-usb-c-cable-wont-destroy-devices/ and https://forums.oneplus.net/threads/in-response-to-the-type-c-cable-discussions.412344/ ) USB-C transfer a lot of power through it, accelerating the process of charging and, consequently, making phone hot. The poor solder who LG's did on the phone start to get melted with the time.
Prevention you can take:
You can make this test in first of all:
https://forum.xda-developers.com/nexus-5x/help/diagnosing-soon-to-bootlooped-phones-t3543830
1- Use only the original cable and wall adapter who comes with the phone
2- Buy only well constructed USB-C cables (maybe it means expensive one, but you will expend more money buying a new phone than a good cable)
3- Keep control of phone's temperature with some app ( I use Cpu Monitor) and never let it exceed 45°C/50°C. If the phone reach this temperature, turne it off immediately (more recommended) or enable battery saver mode.
If the phone suddenly get heat and turn off:
1- DON'T TRY TO TURN ON! Wait until it gets more cold and than try to boot. If it boot, try to make a backup of you important things.
1.1- If the phone is in warranty, send it back and they will send you a new one.
1.2- If not, go to step 2
2- You can try to fix at home. Here are some links:
https://forum.xda-developers.com/nexus-5x/help/rld-fix-red-led-death-t3541536
https://www.youtube.com/shared?ci=i6eu7OK_4t8
3- If it don't work, you can take the phone to someone who works with this and ask for him to make new solder for the CPU.
If anyone know more tips or even solutions, please, contribute to the thread.
**sorry for eventually grammatical mistakes**
Bad quality soldering is really a common problems. Most of my mobile devices - especially notebooks - died because of this. I guess everybody had the problem once where a laptop get bluescreens more often with time until he finally refuses to boot up. Usually, damaged solder connections from chips to the mainboard are the cause for such problems. The solder connection degrades due to thermal and mechanical stress. With time, more and more micro-cracks are emerging with the result that the electrical resistance is increasing. Thus, signal transmission is distorted and bluescreens or crashes occur more regularly until the device dies.
In fact, a thermal treatment can help! The idea is to melt the solder to gain a reflow of the solder which repairs the micro cracks. Although there are semi-professional reflow ovens available on the market, you wouldn't buy one just to repair one device. But you can try do this by using your oven in the kitchen, a hot hairdryer or (if available) hot air gun. The best procedure (independing of the used heat source) is to disassemble the device, detach the battery (!) and if possible remove plastic parts. If these parts can not be disassembled, you can protect them by wrapping them with aluminium foil (it will reflect heat radiation and thus prevent fast heating of these parts). The best case would if you just have the small mainboard with the soldered chips on it. The start the thermal treatment: turn your oven to max. temperature possible, wait until its pre-heated and put the device into it for around 2-3 min. This time should be sufficient to remelt the solder connection (and repair them) and short enough to overheat the plastic parts. If it didn't work, try again with about 30 s longer duration. If you use a hot air gun try to apply the hot air stream only the soldered regions. Usually you can see if the solder gets hot enough. If its working with a usual hair dryer? I dont't know..
I used the kitchen-oven procedure many times and sucessfully revived many notebooks...

50.000 plus km of motorcycle navigating (using Navigon) - so of that in hard rain with the BA "slightly" unprotected ....
So it doesn't like rain or vibration ...
Besides losing the two screws visible on the left and right top edges of the phone, another problem cropped up.
On a recent 6 hour ride, the main connector suddenly became intermittent. I have always hated that connector and I believe it's one of the weaker points on an otherwise less than quality device -but I digress.
I know how quickly the battery will empty using BT and the backlight all the time so I tried to jiggle the cable to get it to work while I was driving. It was not possible, and to add insult to injury, the intermittent connection kept interrupting the MP3s playing and would sometimes cause the SD card to crash, requiring a hard reset. Ugh.
In the hotel I was able to rig the connector so that the device would charge and the next day while at work I figured the device was toast anyway so I took a look inside.
4 screws out from under the battery compartment, and another three screws to get the mainboard loose enough so I could see the connection.
I found the connector so loose that with the slightest touch it fell out in my hands.
Apparently, all of the solder joints had been loosened by the rainwater.
I think this should be a caveat here for all devices left in the rain. I understand that rain water or distilled water is very "agressive". You may be able to get your device to work again. For a while.
I don't think toilet water or moisture from tap water is as bad.
- but again I digress.
Before I went any further, I went out and got an O² XDA-III. HAving safely restored my ability to communicate, I proceeded with the fiddeling.
I was actually able to get the connector resoldered onto the board using a 25+ (pre SMD) year old soldering iron. I actually don't believe it myself but it still works.
I was also able to correct an annoying rattle the phone had almost since I bought it.
The telephone antenna is a raised plastic piece on the back of the board. That raised piece forms a box in which one of the screws for the board onto the frame was "stored". Don't know how it got there but I guess the production people at HTC should listen up.
Well I thought it was fun. anyway.
Hi all.
My LG G3 (stock 6.0 V30n) keep rebooting while I'm using it. I tried the thermal paste mod as suggested in this forum but the situation did not change. Also Wifi and bluetooth do not turn on at all.
I tried a repair center and they said that a new motherboard was needed (price for the spare parts + service = 170$). I did not proceed as I can (easily?) order a spare part and change it by myself for much less.
I already tried to change the battery (bought a new LG-made one, produced in 2016) but this did not solve anything. Also I tried with various factory reseted, cache cleans and even with the latest LineageOS.
Do you think that by changing the motherboard I would be able to solve these issues?
Thanks!
I dont know about this issue, however my thought is that maybe from past overheating perhaps RAM chip or SSD has some poor solder connections. Maybe you could try putting something onto those 2 chips to press them more firmly to the motherboard/soc.

I already tried with a slice of a credit card, plus I put aluminium foil and thermal paste on the CPU and Wifi chips, still reboots
Have you tried putting some pressure on the rear camera connector as suggested by some? If you did, I guess you can try to apply heat to the whole motherboard. I wouldnt bake it. I think you could use a candle to heat it up, while at the same time applying pressure somehow (be creative lol) so that RAM or SSD doesnt fall off.

Unfortunately heat damage to micro soldering joints are usually non-repairable. The silver-based lead-free micro soldering used on it is difficult to repair and it's usually more time and cost efficient to replace the board; that is, if heat damage is causing your problems. I've heard of people actually baking their mainboard in an oven to repair solder joints. This is a ridiculous myth and you risk damaging it further. :silly:
Also, aluminum foil will have the opposite desired effect on heat dispersion. It is not solid and will end up doing nothing, or heating up the chip further. Also, thermal paste in not a good idea to use for this application. Thermal paste is best suited for high-heat CPU and GPU applications. It also expands and hardens after heating up. It may be too late for your device, but for others who are interested, you want to use a 15x15x0.5mm thermal pad. See this post and this post for more information.

Aluminum foil WILL help, not as much as a solid piece od metal but it will transfer heat to the frame of the phone. In my case RAM is bent around the edges because of overheating and it lost contact to the soc. I fixed it by cutting a piece of thin metal I had so that it almost reaches to the side edges of the frame and about 15mm in width. I put thermal paste under it and 0.5mm pad on the soc and now RAM is forced to contact with broken BGA because of the pressure. That fixed the screen fading/flickering as well as overheating. The CPU now idles at around 34c and stays below 60c on most games with some undervolting.
With that said, maybe the same principle could be applied with other chips that cause issues.
Hello folks,
My phone is A505F/DS
It got very little water / chlorhexidine? (COVID-19 fact ) inside the charging port.
After that it just shutdown by itself. I tried to charge . It got "overheated" sign and it won't even start.
So, dug abit over youtube and decided to wash off the type c port with IPA(isopropyl alcohol) , but it is literally impossible to find it now-a-days (again COVID-19 fact) . Also i am in complete lockdown on my side of the country.
So, having no other options in my hand, i brushed the port with plain water and my toothbrush !!!!lol!!!!!!!! and to my utter surprise, it started and working 95% ok. But, now i am having one issue. Randomly, when i charge or do nothing but surf internet or YouTube , it can rarely notify " device overheating.. bla ... bla..bla" .
So i installed couple of temp monitoring apps and observed, this phone has only one temperature sensor? Called "battery temp ". Whenever it reaches 50°c it stops battery charging (obviously lipo safe operating temp range's upper limit is around 50°c). And when it goes around 59°c level it stops all phone functions apart from emergency call .
Now, what i need help about, is it possible to change the threshold level of cutting of the charging of the battery to 53°c around? Coz i have seen that even if the device is like of room temperature the "battery temp" hangs around 50-52°c and suddenly goes back to normal.
Plz help. In this lockdown, this little digital entertainment device is what i am passing my most time with And trying to get a living in this tough times.
Turn off fast charging if you updated to Android 10 (it's new feature in OneUI 2.0), also try to not use phone when it's charging.
Ok. But i am still on android 9
Ok . Not using while charging is helping i guess.
I will report back if anything happens
You cant fix this peoblem just by ignoring the high temperatures, its obviously a hardware issue and you made it worse by using water to clean the charging port. Water is very corrosive to electronics and may create shorts. You phone probably need to be desassembled and properly cleaned with isopropyl alcohol. Some components may need to be replaced(i hope no). Its imo dangerous to continu using it as it is

I cant even open the phone. Any tutorial to open it by simple tools?
[Update] today i was just surfing the internet, and the temperature suddenly shoot up to 62°c but the device on hand was cool enough to consider the temperature reading false . And suddenly it went back to 44. Again up to 55.... etc etc. I kept the phone @ Refrigerator for a min . And for last 8 hrs its fine... weird lol

Yeah . Right?
Again today it randomly shot upto 63°c. Like from 45°c . It was jumping around like crazy for about 15 minutes.... now again normal.
I don't know what to do
Quick update.
Almost a month no problem faced
What i did..
1. Turned off fast charging (i think this is the most important thing to do)
2. Not using the phone while charging
3. Keep the phone @floor while charging( keeps it cool i guess?)
I kept it away for 2 days wrapped i tissue paper untouched and it seemed to be back to normal.(so far its been 3 2 days since the problem stopped happening)
My phone like your phone break and say over hearting error
Just gooing to your guaranty service this error for hardware problem
Any update on your phone temperature? Is it going back to normal?
I just had this same exact problem with my a50. I asked Google before I bought it if the A50 was water resistant and found 4 sites that said yes. Turns out it isn't and I cleaned the phone after shopping in lockdown and it started malfunctioning. I just successfully fixed it last night by watching a YouTube video that shows disassembly and then removing very small units from the charging port sub board. You only need a 00 Phillips screwdriver, a piece of plastic water bottle and tweezers or xacto blade. It shows how to remove the malfunctioning thermistor
Replace the charging PCB to fix the issue
In most cases, you need to replace the charging board to fix the issue. There is no other way to get rid of that problem:
Could you share the link to the video clip? Thanks
https://www.ifixit.com/Answers/View...ge+or+turn+on+-+Overheating+icon#answer649037
This is what I did to fix mine. Removed those 3 components that @Gspain2020 was talking about. I used a soldering iron and a needle, but tweezers or an exacto knife will probably be better. Or you could get a new charging daughterboard which should also fix the problem.
If you remove those components, the phone will be unable to detect the temperature, which can be dangerous if you allow it to overheat. Instead of the phone managing the temperature, you must stop using it if it gets too hot.
Hey all, I have had my Galaxy Note 10 for almost a year, and the other day I accidentally dropped it and ever since then I have been getting the message that my phone temperature is too low and that charging would resume when my phone returned to a normal temperature.
So I did some research and found that my phone's temperature sensor is broken and that I would need to get the wireless charging coil replaced as that is where the sensor is located. I also saw that it was a cheap repair and would be covered by warranty. Unfortunately because of the root it would not be covered by warranty and was actually very expensive as the part needed to be imported.
I ran a few tests and apparently my phone is at minus 30 degrees Celsius. When I got a report sensor, it says that it isn't even there. Clearly the sensor is broken. (Look at attached URLs for screenshots)
The strange thing is though, that I can still use my phone whilst it is plugged in. So obviously it can still use power, but not store it in the battery. Because it can still use power and since it is rooted, surely there is a way that I can change the minimum temperature at which the phone can charge? Or delete the piece of software/file that gives jt any limit at all?So I wanted to ask, since my phone is rooted, surely there must be a way I can "override" the error and charge my phone regardless.
So I looked for ways to charge my phone regardless and came across thermal throttling, which I know is dangerous, but surely because my phone isn't actually "low temperature" if it was well managed, it wouldn't be too unsafe? And would thermal throttling even work as I know that it helps to run your phone at HIGH temperatures, but what about low ones?
So the last thing I wanted to say was that with the phone being rooted, is there some app that can allow me to ignore this warning (override it) as there is obviously a file that prevents charging when the temperature is low. Could this file be altered/deleted, or could the while thing just be ignored. Or would thermal throttling work?
Please leave some feedback, anything is appreciated.
Also please link at the attached URLs for screenshots.

If that's the only temp sensor for charging you should have it as it won't shut it down if it gets too hot.
A Li meltdown isn't pretty.
Is the bad sensor in the battery???
If so simply replacing the battery might fix the issue
What is the problem?

The repair centre that I took this phone to said that the MOTHERBOARD was broken. I think they were mistaken as this is not a problem caused by broken motherboard. Research says the sensor is in the Wireless Charging Coil so I might try fix this. but then what is it about the battery? Which part is broken?
And in the meantime is their any way to override this message with a rooted phone (my original question)
It a thermistor on the wireless charging module or a bad connection going to it. A broken multilayered mobo solder trace can be repaired if it's just one trace and it's beginning/end point isn't under a flat pack.

So are you saying that either the connection (on the wireless charging COIL) from the coil to the battery is broken, or the connection port on the battery might be broken? Is it definitely NOT a motherboard issue?
If so does the wireless charging coil/entire phone battery need replacing?

I don't see a listing under sensors for a internal batter sensor... it appears to be external.
I didn't tear it down.
The sensor or connector issue is more likely but not guaranteed.
You could take an ohmmeter to the sensor to check if it's the culprit. It appears to be on the charging coil assembly, right?
If so a cheap fix.

There is only one sensor and its attached to the wireless charging coil, that was the case with the s7 edge back in the day. I see no reason why that would be different now. Its purpose is to monitor the battery and coil temps.
Replacing the wireless charging coil should fix it. You should be able to order one for pretty cheap. its could also just be a loose connection. If your warrenty is void then you might as well open it up (if you have the tools and skill) to confirm the wireless charging connector is seated properly into the motherboard. (since you dropped it, its likely its just come loose)

This could be true if the service tech was mistaken. All the OP knows for sure is the chipset isn't getting the temp data.
A good repair center -maybe- could do mobo level repairs. Sammy certainly could.
Remember no repairman likes an open box special.
The OP can try replacing the coil but maybe no better off if it needs a mobo. In the back of my mind I still wonder if the battery pack has a temp sensor the phone is using as well. I see no indication of that but it seems like a logical place for it especially given Samsung's history of exploding batteries.
If the OP goes for a battery replacement there's much more risk of damage involved.
Tough call.
Note: A high G impact can even break internal IC connections. A 3 foot drop onto concrete can generate sufficient G loading to do this. So there's that...
A good case spreads the G force loading over a greater timeframe and lessens it by absorbing some of the energy as well transforming it to heat.
These are heavy, expensive phones with very little impact protection. Get a good case like the Bolt.

It be a happy ending if so...
and not the first time a repair tech was wrong.
Maybe the OP could try a better repair shop if they don't feel up to using a heat gun and popping off the back panel. This is one of the easiest repairs for these phones but still requires considerable care to do. Depends on the OP's skill level and having the minimum tools required.

Well said
Don't know if this will help but I have the same problem with my Note 10+. Mine has a cracked back cover and the faulty temp sensor issue seems to emanate from this because as soon as I slapped on a back cover, the issue resolved itself. I'll replace the back cover eventually but it seems the loose panel might be the issue.
Good luck.

Welcome to XDA
There's a temp sensor on the wireless charging coil assembly I believe. There are a bunch of ribbon cables as well, one could be loose or damaged.
Rear covers are cheap, replace it before the phone gets severely damaged. Get a rear cover seal too. Water kills phones.
Always keep the N10+ cased or it will get damaged. The Zizo Bolt is cheap, provides excellent drop protection and makes the N10+ easier to use.
Okay, hello XDA Forums peoples! Ive been lurking here for like a decade. I feel bad for bothering you nice people, but now I'm at my wits end with this phone.
Okay, so, long story short:
Z Fold 3, let it run the One U.I. 4 update, bricked the whole phone, wouldnt come back on. This happens a week away from being out of warranty. So i get samsung to agree to let Asurion/uBreakiFix repair it (I almost always fix my own electronics, I hate Asurion, I've had problems dealing with them before, but its free so whatever). Well they get it working, i asked what they did and they were basically like 'uhhh idk'. I assume it was just an 'unplug the battery and plug it back in' kind of thing.
Anyways fast forward to a couple months ago. Im walking along the creek, i always keep my phone in my backpack for safety. Zipper on my backpack comes open some, phone falls out and directly into the water for about 3-5 seconds. Goes black within 15 minutes. Alright, so it seems like maybe the boys who worked on this didnt seal it back properly. Whatever.
I let it dry for about 4 or 5 days. Comes back on, everything works except the front screen's digitizer(which is cool for me, because the inside screen still works fine) and its reporting too cold to charge, so now once the battery runs out i have a new foldable brick! Yay! I check the battery temperature thats reported in settings and its completely fine. I hit it with a hair dryer for like 5 minutes to try and trip the thermometer, and nothing happens.
I tried some cheap shots in the dark, i replace the USB charging board, i replace the wireless charging coil, both of which have thermistors on other older samsung phones, so i figured it was a decent guess. Still too cold to charge.
So I find a schematic, or not exactly a schematic, but like a boardview, i guess. So at least i know where the thermistors are to check them. Theres about 10 thermistors on the main and sub boards. 5 of which are covered by metal shielding which i am just terrified of trying to remove, mainly because i havent done it before. So i check the other half.
The thermistors used in these phones are like inverse, so they have less resistance for higher temps and more resistance for lower temps. If one of them is dead, it will have like "maximum resistance", right? Which would report the coldest possible temperature, right? So that all makes sense, to me at least.
The 5 i can get to with my meter to check, they seem to work completely fine. From what research ive done they seem to be like 100k resistors when measured at ~70 degrees f, and i can watch the resistance go up and down when its cooled or heated past that temperature. Okay, perfect. That all checks out.
Because the other ones are under some metal shielding, i assume theyre most likely fine because any water would have a harder time getting in there. So i skip to the most expensive option so far: i buy two replacement batteries. The schematics do not include the battery, so i dont know where the thermistors are on my current batteries to check them, if that was the problem.
Well, batteries came yesterday, i pop them in, still too cold to charge. I've already ran the phone dead checking it, so i cant do any further diagnostics with the phone on. And now the most i get is a Yield sign with a thermometer in it when i plug it in.
Okay, so... Idk?? This problem is starting to get over my head. What do y'all think? It seems like my options are becoming more limited and expensive.
I can try and put a big blob of solder on the top of the shielding and pull it off to check the remaining thermistors, which seems to be how people remove those things. I also have have hot air at my disposal, which is always risky with tiny things because too high airspeed might blow components away on the board and then i'll probably cry.
It could just be a connector somewhere on some flex cable? Maybe? I mean like maybe what if one of them is for reporting temperature, and water corrosion is stopping it from sending a signal through???
Im fine with doing whatever, but i just want a charged battery first so i can recover my data before i do anything that drastic. I mean, back in the day they had 4 big pads on a removable battery. You could buy a universal samsung battery charger or rig a USB cable to charge it, but I have literally no idea what to do here. Does anyone know of some specialized battery charger that will connect to these flex cables?? That would be a gigantic help right now. Or if i knew where to get a Z Fold 3 just to pop it open and charge my battery with? Or maybe just sit there for 2 hours holding two wires to the positive and negative pins?!??!?? I dont know. Someone throw ideas at me, please!
Might be worth buying a bench power supply and either injecting voltage through the phone or connecting it to the cells to trickle charge them back up? Im not an expert it these just throwing ideas
